Unlock the full potential of your Arduino Nano with the Nano I/O Expansion Shield. Specifically designed to solve the common problem of messy wiring, this board breaks out all digital and analog pins into easy-to-use 3-pin headers (Signal, VCC, GND). It is the perfect companion for prototyping, allowing you to connect sensors, servos, and other modules instantly without a breadboard.

Why You Need This Shield:

  • Simplifies Wiring: No more tangled jumper wires. Connect devices directly using standard 3-pin sensor cables.
  • External Power Support: The on-board DC barrel jack allows you to power high-current devices (like servo motors) that the Nano's USB port cannot handle alone.
  • Broad Compatibility: Designed for Arduino Nano V3.0, but adaptable for older versions and compatible clones.

Key Features:

  • Plug-and-Play: Breaks out all 14 Digital I/O pins and 8 Analog pins with dedicated power and ground rails.
  • Servo Ready: Provides stable external power input specifically for driving servo motors.
  • Communication Friendly: Dedicated pins for I2C (SDA, SCL) and UART (Rx, Tx) expansion.
  • Stable Power: Includes 3.3V output and AREF output for precise voltage reference.

Technical Specifications:

  • Compatibility: Arduino Nano V2.x / V3.x
  • Digital I/O: 14 Pins (servo style with GND, Power, Signal)
  • Analog I/O: 8 Pins with power output and GND
  • PWM Pins: 6
  • Interfaces: I2C Expansion, UART
  • Power Input: DC Barrel Jack for external power supply
